If t+8=-12 what's the value of t + 1

Answers

To find out what t + 1 is, we first must find out the value of t.
We know that t + 8 = -12, so all we need to do to solve for t is subtract 8 from both sides.

t + 8 = -12

t + 8 - 8 = -12 - 8

t = -20

So now that we know the value of t, all we need to do to find t + 1 is insert the value of t into the variable and solve.

t + 1 = ?

-20 + 1 = ?

-19

And there we have it.
t + 1 = -19
Hope that helped! =)

the reason it gives us t + 8 = -12 is because they want us to figure out what t is. this is very simple trust me:) given our problem.
t + 8 = -12 what we have have to do here is isolate t alone. lets subtract 8 from both sides.
t + 8 = -12
- 8 = - 8 the 8 on the left hand side of the equal side is canceled out! and we have to subtract 8 from -12. lets do the math:)
-12 - 8 = -20 well lets see what we have left of our problem.
t = -20
hey we have our answer we know that t = -20
but the question is asking us to find the value of t + 1
well lets plug -20 for t
-20 + 1 = -19 since we are adding 1 it moves plus 1 towards the number zero.
so whats the answer? you may be asking..
-19
have a good one :)

Monica walks 2 miles each day Monday through Friday. She walks 3 miles on Saturday. She does not walk on Sunday. Monica calculates that she will have walked 127 miles after 29 weeks.What is an estimate for the number of miles that Monica will have walked after 29 weeks? Is her original calculation reasonable?

137; her original calculation is reasonable

145; her original calculation is not reasonable

310; her original calculation is reasonable

390; her original calculation is not reasonable

Answers

lets calculate how much she walks each weeks and then we multiply that by the number of weeks.
weekWalk = 5(2) + 3 = 10 + 3 = 13
therefore, she walks 13 miles per week, if she walked for 29 weeks then we have:
total walked =(29)(13) = 377
so she walked 377 miles total, so her original estimate is not reasonable

Answer

390; her original calculation is not reasonable

Step-by-step explanation:

What is the elapsed time between 2:45 and 6:55?4 hours and 10 minutes
